IMPROVEMENT 1N Bom-CLAMP.

The Schedule referred to in these Letters Patent and making part cf the same,

being broken'a-way to show the construct-ion.

Figure '2 is a detail sectional view of the same, taken through the line x x, g. 1.

Similar letters of reference indicate corresponding part-s.v

My invention has`for its object to furnish an improved clamp for holding a round-headed round bolt, or a bolt which, from any cause, has become loose in the wood or iron, to enable the nut to be turned olf when said nut maybe tight-fitting or may have become rusted on.

These are the general purposes which my invention are intended to snhserve; but its more particular object and its most valuable purpose is to operate upon bolts in setting tire. Setting bolted tire has been a part of my business for many years, and I have felt the necessity for a long period of some improvement t-o facilitate this branch of labor.

a Steel or hard point.

It also consists in the construction and combination of the various parts of the device, as hereinafter more fully described.

A is the clamp-frame,'the lower arm of which is made branched, as shown in fig. 2, to firmly support I the wood or iron that contains the bolt, the nut of which is to be removed, against the action of the clamping-screw, aud at the same time furnish space enough around the nut for the wrench to take hold of and operate the said nut.

Through the end of the other arm of the clamp A is formed a screw-hole, into the threads of which tit the threads of the clamping or hand-screw B. The point lof the hand-screw B should be steel, so as to take 4hold of the head of the nut with sufficient strength to hold it against the action of the wrench.

In lusing the device, the clamp A is put,over the -wood or iron containing the bolt to be removed, in

such a way that the nut to be operated upon may be,

between the branches of the lower end ofy said frame YVhat I .claim as new, and desire to secure by Letters Patent, is-

A til'efbolt clamp, formed of the frame A, branched at the lower, and having a threaded nut in the upper end thereot`,'combined 'with a clamping-screw, B, having a hard point at its extremity, the said parts being constructed and operating together in the manner described.

' The above specification of my invention signed by me, this 7th day of May, 1869.
